The Solis S6-EH3P125K10-NV-YD-H is a 125kW three phase hybrid solar inverter built for high voltage battery storage. It sits at the top of the Solis Solarator 80 to 125K series and brings solar, storage, grid and generator inputs together behind a single control point, aimed at commercial and industrial sites where an outage is expensive.

Three phase hybrid solar inverter features

• Solar input: recommended PV array up to 250kW, maximum input voltage 1000V, MPPT range 150V to 950V across 10 trackers and 20 strings, each input rated at 42A.
• Battery ports: two independent high voltage battery ports from 300V to 950V, each with its own BMS connection, charging or discharging at up to 100A per port for up to 200A combined.
• Backup switching: under 10ms transfer from grid to off-grid for a single unit, with 140% of rated power for 10 seconds and 160% for 200 milliseconds to help start motors and pumps.
• Parallel operation: multiple units run together up to 1.25MW, with switchover below 20ms in a parallel system of up to 6 inverters, and each phase carrying up to 33% of rated power.
• Monitoring: 7 inch LCD, Bluetooth and the Solis app for local setup, with Wi-Fi, LAN and Bluetooth built in and 4G optional.
• Enclosure: IP66 rated with intelligent redundant fan cooling, operating from -25°C to +60°C and up to 3000m altitude.

Battery and generator support

Solis rates the battery range for modules from 100Ah to 314Ah, communicating over CAN. A dedicated 125kW generator input, weak grid control and a utility bypass keep loads running when supply is unreliable. Solar and storage work together for export limiting and dynamic reactive power compensation, and the inverter supports both DC and AC coupling with a three in one interface for on-grid PV, wind power and diesel generators.

Applications

Suited to factories, large farms, distribution centres, cold stores and other commercial sites needing peak demand reduction, export limiting or backup for critical loads, including sites with a weak grid connection or a standby generator.

Installation notes

This is a high voltage battery inverter for compatible lithium systems between 300V and 950V; it is not suitable for 48V battery banks. Solis lists G99 among planned grid connection standards for this range, so confirm certification status before specifying it for a UK grid connection. Installation and commissioning must be carried out by a qualified installer with correct DC fusing, AC protection, surge protection and earthing. The unit weighs 170kg and measures 1174 x 814 x 400mm.
